280AI load development

[staghunter]

I recently bought a 110 Ultralight in 280 AI. I have finally acquired some 150gr accubond to try to work up a ladder test. I wanted 168gr ABLR but that's not happening at this time. Wondering if anyone has used these components and a particular powder was a standout. If so where you seen a node or do we see a certain velocity that give better grouping. I'm thinking I'm going to really like this gun. Thanks in advance for any help.

There is a ton of info on here but todays answer is what you can actually purchase.

One's that work are RL-23, RL-26 and 4831...

Good luck with the Ultralight! I love mine in .308.

No 23 or 26 but do have shortcut. What about H1000 or Retumbo.

 

[staghunter]

I have several I can use. 4350, rl22. Was just hoping someone had made the journey before me. Don't want to use up all my bullets and primers going through several tests.

H4831sc with the 140-150 grain bullets. For heavy bullets rl23 or n565 or n560. I use h4831sc with 140s at 3200 FPS.

4350, 4831, hybrid 100v are the three I would look at if you have no rl 23 or 26

Thanks I'm thinking H4831 will be my first endeavor.

I use 62grs of 4831sc, Federal 210M, Nosler case, 140 gr accubond... Shoots amazingly well. I can't remember the velocity though off the top of my head.

Here are some of the groups I shot during load development. Pictures are sideways but you get the idea.

the 168 ablr is available at 3rd generation

I'm shooting the 143 Hammer Hunters and Re 23.
Re22 will work, but not as temp stable. H4831SC is a good stable powder. Not as fast as RE but reports are solid groups.
ABLR 175 in my 7 mag were beyond disappointing at distance. Many others complain of flyers. Regular accubonds may be fine.

Thanks everyone for your input. Let you know how it goes.

Try H4350 is stable, it's quicker than H4831SC if you can get it.

Big 280ai fan, can't get Hammers to group. Doing best with factory 168 Berger's. Anyone have a favorite recipe that would come near Federals 168 Berger's?

What's your twist rate? That maybe the problem in not turning the bullet fast enough.
